COMPRESSOR OIL LEVEL CHECK DAILY CHECK
Check the compressor oil level daily, after running
the compressor.
1. Stop the compressor with closed air outlet valve
(3) and let it rest for a short period, to allow the
system to relief pressure inside the vessel and
settle down the oil.
2. Check the oil level via the oil sight glass (1). The
oil level must be in the upper half of the glass. If
the oil level is too low, add oil via the oil filler plug
(2).
3. Top up with oil until the oil level is at the upper
level as indicated on the label (1).
4. Reinstall and tighten the filler plug.
CHECK AFTER A LONGER PERIOD
WITHOUT RUNNING THE COMPRESSOR
1. Check the oil level via the oil sight glass (3). The
level must be in the upper half of the glass.
2. If the oil level is too low, remove the oil filler plug
(2) and check if there is still oil in the vessel.
• No oil in the vessel: Top up the compressor
with oil until the oil level is at the upper level
as indicated on the label and follow the steps
as described above in Daily check.
• Oil in the vessel: Start up the unit to warm up
and give time for the thermostatic valve to
open. Stop the compressor with closed outlet
valve (4) and follow the steps described above
in Daily check.

The compressor oil level needs to be
checked with the compressor in an
horizontal position after running the
compressor to warm up so that the
thermostatic valve is open.
Before removing the oil filler plug,
ensure that the pressure is released by
opening the air outlet valve (4) and
checking the vessel pressure on the
controller or the pressure gauge.
At temperatures below 0°C, you have to
load the compressor to be sure that the
compressor thermostat will be open.
